Who started it? Cassandra Postema, a graduate of London's Central Saint Martins College of Arts and Design, is a fashion designer with a social conscience. From her early days upcycling vintage finds in the British capital and selling them to high-end boutiques, she's had an eye for potential. Since moving to Hong Kong, she has set up a social enterprise, Emi&Eve, which focuses on collaborations with disadvantaged creative types making eye-catching items of jewellery with stories behind them. Her latest collection, From Bullets to Beauty, is a collaboration with a Cambodian who lost his family to the Khmer Rouge. Chantha Thoeunthe specialises in recycling bullets and bomb casings by melting them down and transforming them into unique pieces.

Why we love it: the concept of turning dark, destructive items found in the fields of Cambodia into objects of beauty is brilliant and the outcomes are as original as the idea.

What we'd pick: the Maxima clutch (right centre; US$250), made entirely out of a bomb casing, is a winner, its hard exterior and green stone setting making it a real statement piece. The Iris Gold (below right; US$110), with its simple gold chain and clasp, has a more vintage feel to it and the soaring bird pendant (above right; US$35) is another favourite.

Where can I get it? Emi&Eve is available at at Polkadot (2/F, 29 Hollywood Road, Central, tel: 2521 0636.
